Description
The CD22301 monolithic PCM repeater circuit is designed
for T1 carrier systems operating with a bipolar pulse train of
1.544Mbits/s. It can also be used in the T148 carrier system
operating with a ternary pulse train of 2.37Mbits/s. The cir-
cuit operates from a 5.1V ±5% externally regulated supply.
The CD22301 provides active circuitry to perform all func-
tions of signal equalization and amplification, automatic line
buildout (ALBO), threshold detection, clock extraction, pulse
timing and buffered output formation.
